Embodiment Construction
[0057] The present invention will be described in further detail below in conjunction with the examples. The following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.
[0058] In today's mathematical geometry and teaching models, they are all teaching models made of solid bodies or a combination of solid bodies.
[0059] The purpose of the present invention is to provide a new kind of "virtual and real combination" of solid bodies to form a "dynamic deformation plane" with dynamic deformation of "virtual moving edges", or to form a "virtual deformation plane" with virtual moving edges and "overall virtual edges". "Dynamic deformation three-dimensional body" of "moving plane" and the recombination of these bodies to form a higher-level dynamic deformation geometric mechanism of various combinations. The dynamic deformation laws and rules of these shapes and their deformation limit critical or special shapes, variou...

The invention discloses a deformation unit body mechanism of virtual and real combination rules. Firstly, two crossed straight rods of equal lengths are adopted for composition, the hinged part of thecrossed straight rods is a midpoint of each straight rod, and then a dynamical deformation real movement rectangular plane is jointly formed with connecting lines of all end points of the crossed straight rods and the crossed straight rods as diagonal lines; a plurality sets of crossed straight rods are sequentially combined, the two adjacent ends of each set of crossed straight rods are hinged to the adjacent ends of another set of crossed straight rods through directional joints respectively, and the hinged parts of the ends, located at the relative same side, of each set of crossed straight rods sequentially serve as connecting lines to form a pair of relatively parallel regular polygon virtual movement planes; in this way, a line-body-surface variable dynamic deformation polygonal prism of the virtual and real combination rules and the multi-stage combination mechanism thereof are formed. By means of the deformation unit body mechanism, people can very visually see and understandnew concept principles of virtual and real combination of dynamic deformation, combination principles and shape change rules of the mechanism.
Description
technical field [0001] The invention belongs to the technical field of three-dimensional virtual-real combined deformation structures, and relates to a deformable unit body mechanism with virtual-real combination rules. Background technique [0002] In today's mathematical geometry and teaching models, they are all teaching models made of solid bodies or a combination of solid bodies. Therefore, these models can only display static shapes and structures, but cannot intuitively and quickly understand the dynamic change process and relationship of three-dimensional structures, which is not conducive to stimulating imagination and creativity. SUMMARY OF THE INVENTION [0003] Aiming at the needs of the prior art, the present invention provides a deformable unit body mechanism with a combination of virtual and real, the deformable structure model can be intuitively, quickly and clearly let people see and understand, these dynamic deformation virtual and real combination The ne...
